This publication relates to a tubular transom in particular for temporary structures, such as scaffolding or false work and similar structure, having ends configured to be connected to verticals at node sections arranged at intervals on the verticals. Each end of the transom comprises a fastening device with an integrated profile part, releasably attached to the tubular transom in an opening at the ends of the tubular transom. The transom comprises a first and at least second elongate, parallel and hollow tube elements, interconnected at least at each end by intermediate integrated web plates, rigidly fixed to said at least two tube elements. A contact surface of the opening in the first tube, is transversally arranged relative to one or more web plates. A contact surface of the opening in the second tube is transversally arranged relative to one or more web plates. The opening at the ends of the transom having at least partly a complimentary shape.

Disclosed herein is a clamp for interconnecting two components of a support apparatus such as components of a shoring apparatus for concrete forming systems. A clamp member having a moveable jaw is received for pivotal movement in a housing that is secured to one of the components. A plurality of flutes disposed at an angle to the pivot axis of the clamp member are received in coacting recesses in the housing and a proximal cap maintains the desired position of the clamp member within the housing. Axial movement of the clamp member will pivot the swing arm and a coacting, moveable jaw toward a fixed jaw formed in the housing to releasably secure the clamp to the other component.

A suspended scaffolding connector includes a central spine comprising an anchor connector at a top end thereof, a bottom lug at a bottom end thereof, and a top lug situated between the anchor connector and bottom lug. The connector further includes at least one top truss connector attached to the top lug and at least one bottom truss connector attached to the bottom lug, where the top and bottom truss connectors are configured and spaced for structural connection to top and bottom connectors of a scaffolding truss. The connector also includes top and bottom truss ledger connectors attached to the spine and situated between the top and bottom lugs and adapted for connection to a scaffolding ledger, and the anchor connector is adapted for connection to a suspension anchor and to support the scaffolding truss through the top and bottom truss connectors.

Folding rail assembly for a scaffold, comprising an upper rail part, a middle rail part, a first post, and a second post which are mutually hingedly connected for adjusting between a folded-in configuration and a folded-out configuration. The first post is provided with a coupling hook structure to suspend the first post from a rosette of a standard of the scaffold in an opening of the rosette with play. At the coupling hook structure a locking hook structure is provided which is configured for, depending on a rotation position of the locking hook structure relative to the rosette, counteracting the first post, by moving up, being brought out of its state suspended from the rosette. By rotation of the rail assembly around a rotation axis parallel to the standard, the locking hook structure can be brought in a locking position to counteract the suspended post coming loose.

A lightweight, multifunction scaffold comprises first and second ladder frames, and an adjustable height platform configured to be supported between the first and second ladder frames at a user selected height in an adjustment range. The multifunction scaffold can be linked together end to end with other similar scaffolds to provide a longer working surface.
